Patented Sept. 7, 1954 UNITED STATES PATENT OFFICE AUXILIARY BARBERS CHAIR Bogoia Strezo, Minneapolis, Minn. Application September 17, 1953, Serial No. 380,840 8 Claims. (Cl. 155--131) This invention relates to auxiliary .fbarbers chairs. More particularly, it relates to a novel type of auxiliary chair usable by a barber in cooperation With the conventional barbers chair to provide a more satisfactory support for children while cutting their hair.

Most auxiliary devices for use in conjunction with a conventional barbers chair to provide a support for children While the barber cuts the hair, are unsatisfactory because the upright back portion of the conventional barbers chair is constantly in the way of the barbers arms While he is performing the hair cutting operation. In addition, most of these devices tilt or tip easily so that an unsteady and unsatisfactory support is provided for1 the child. Also, these devices are generally crude and present an unpleasing appearance and in addition have no other use to which they may be put except in conjunction with the conventional barbers chair. My invention is directed toward eliminating at least some of these undesirable attributes.

A general object of my invention is to provide a novel and improved auxiliary barbers chair of cheap and simple construction.

A more specific object is to provide a barbers chair ,constructed to be easily operable by the barber and to provide a means for supporting the child in a manner such that the back portion of the conventional barbers chair will be out of the way so as not to hinder the barber during the hair cutting operations.

Another object is to provide an auxiliary barbers chair which can be quickly and easily positively secured to a conventional barbers chair so as to hold the auxiliary chair in rigid position to ypreclude tipping or tilting of the same.

Another object is to provide an auxiliary barbers chair which may be utilized in conjunction with a conventional household stool in addition to being usable in yconjunction with a conventional barbers chair.

Another object is to provide an auxiliary barbers chair which when used in conjunction with a conventional household stool may provide a highly satisfactory substitute for a Ibarbers chair within the home.

Another object is to provide an auxiliary barbers chair which may be, if desired, attached to a barbers stool so as to permit the barber to raise and lower himself While cutting adults hair in the conventional barbers chair.

f These and other objects and advantages of my invention will more fully appear from the following description made in connection with the accompanying drawings, wherein like reference characters refer to the same or similar parts throughout the several views, and in which:

One embodiment of my invention may include, as shown in Figs. 1-6, a base member indicated generally as B adapted to be Iplaced upon and supported upon the upper surface of a seat I0 of a conventional barbers chair indicated generally as C. As shown in Fig. 1, the barbers chair has the conventional opposed side arms I I and I2 and is elevated and lowered by a conventional hydraulic mechanism shown partially in Fig. 2 and indicated as I3. The bottom surface of the base member B has a recess as at I4 formed therein adjacent the forward and peripheral portions thereof. A U-shaped lclamp member I5 extends through a slot I6 formed in the bottom surface of the recessed portion of the undersurface of the base member B and has its base I 5a and one leg |513 extending downwardly from the base member B. The other leg I5c of the U-shaped clamp member is pierced by a vertically extending eX- ternally threaded screw I1 which is journaled in the upper and lower surfaces of the base member and which has a knurled knob I8 at its upper end. The portions of the leg I 5c through which the screw I'I extends are internally threaded to cooperate with the threads of the screw II so that the U-shaped clamp member I5 is threadedly engaged and driven through rotation of the screw l1 about its longitudinal axis. By rotation of the knob |8, the U-shaped clamp member may be raised or lowered as desired relative to the base member B. When the clamp member I5 is raised to its highest position it will be noted that the lower surface of the leg |51) extends in the same plane as the general plane of the lower surface of the base member B.

Disposed at opposite sides of the base member B is a pair of opposed arms or arm rests i9 and 20. These arm rests lil and 26 are slidable laterally relative to the base member B and extend upwardly therefrom as best shown in Fig. 5. Se-

cured to the arm rest I9 is a U-shaped frame 2| and secured to the arm rest is a correspondingly shaped U-shaped frame 22. As best shown in Fig. 1, these frames 2| and 22 extend inwardly from the arm rests |9 and 2E! toward each other and are connected by a transversely extending externally threaded shank 23'. The transversely extending shank 23, as best shown in Fig. l, extends through the bases of the U-shaped frames 2| and 22 and are in threaded engagement therewith so that rotation of the shank 23 about its longitudinal axis will cause the U-shaped frames 2| and 22 to move toward or away from each other, depending upon the direction of rotation. This, of course, is caused by the one end portion of the shank 23 being threaded in a direction opposite to the other end portion thereof. Each end of the shank 23 is journaled on the base member B as best shown in Fig. 1. A knurled knob 24 is provided to facilitate rotation of the shank 23 about its longitudinal axis. Rotation in one direction of this knob will cause the arm rests i9 and 23 to extend laterally so as to engage the inner surfaces la. and |2a of the arm rests l and I2 of the conventional barbers chair C. By turning the knob 2d suciently, the arm rests i3 and 20 will rmly engage the inner` surfaces of the arms and l2 of the conventional barbers chair C and thereby firmly secure the base member B to the conventional barbers chair in a manner so as to positively preclude tipping of the same.

Mounted upon the base member B at the rearward portion thereof and extending horizontally and rearwardly therefrom is a plate member 25. Rigidly secured to this plate member and extending upwardly therefrom is a pair of relatively large channel members 26 and 21. The channel member 26 has a vertically extending gear rack 28 secured to its inner surface. A box-like member 29 is provided to ride upwardly and downwardly between the channels and 21 and in engagement therewith. This box-like member 29- is open at its upper and lower ends and is comprised of four relatively small U- shaped channel members 33, 3| and 32, 33. It will be noted that the channel member 3@ extends in an opposite direction to the channel member 3| and that the channel member 32 extends in an opposite direction to the channel member 33, and that each of these channels engages one leg of the larger channel members 26 and 21. The channel members 3i) and 3| are secured together at their upper and lower ends by cross bars ask are the channel members 32 and 33 in order to complete the box-like structure 29.

A plate member 34 is fixedly secured to the inner legs of the channel members 32 and 33. A second plate member 35 is xedly secured to the inner legs of the channel members 36 and 3|. A third plate member 36 is fxedly secured to thev outer legs of the channel members 30 and 3|. Fixedly secured to the outer surface of the plate member 36 is a metal disc 31 which is constructed as shown in Fig. 4 to have a plurality of internally threaded holes 33 formed therein at opposed and regular positions. Indicating prongs 39 extend outwardly from positions opposite each of these holes.

Rotatably mounted upon and extending through the two plates 34 and 35 is a shaft 40. This shaft carries a gear 4| in xed relation thereto so as to cause the gear to rotate with the shaft. The gear 4| is of suflicient size and pitch to cooperate with the gear teeth of the gear rack 2S during its rotation. The shaft 40 extends outwardly through the disc 31 and terminates in a relatively/large head member 42. This head member has an internally threaded opening 43 formed therethrough and positioned so that a threaded lock pin 44 will, when threaded to extend through the head member 42, engage the threads of the openings 38 so as to lock the head member 42 to the disc 31 at that position.

Fixedly secured to the outer legs of the channels 32 and 33 is a metal plate 45 which in turn is rigidly secured to a seat member 46. The seat member 46 is disposed horizontally as best shown in Fig. 6 and extends forwardly from the plate 45 and is disposed above the base member B. This seat member 46 can move vertically relative to the base member B and its movement is controlled through the adjustable control. mechanism comprised of the `aforedescribed channel members, the gear rack 23, the gear 4| and the means for rotating the latter.

Figs. 7 and 8 `show a modied form of adjust- 'able control mechanism which may be utilized in conjunction with the remainder of the invention to control the vertical movement of the seat member 46. This modified form may be comprised as shown of a horizontally extending plate E which is xedly secured to the base member B and to an upstanding channel member 5|. This channel member has a pair of spaced guide straps 52 and 53 extending upwardly there through as best shown in Figs. 7 and 8. A vertically extending slot 54 is formed in the forward wall of the channel member 5| and through this slot a, vertically extending upright plate member 55 extends. The plate member 55- has the seat member 46 xedly secured to one of its side edges and has an internally threaded member 56 xedly secured to its other side edge as best shown in Fig. 8. The internally threaded member 5S has outwardly extending ears 51 and 58 which cooperate with the guide straps 52 and 53 topreclude rotation of the internally threaded member 56 in a horizontal plane. A vertically extending shank 59 which isexternally threaded and in threaded and driving relation tothe internally threaded member 56, extends through the member llty and is provided with a knob 6U at its upper end to facilitate rotation of the shank about its longitudinal axis. The shankv 59 is journaled at its lower end as at 6| in the plate 50.

In use, my auxiliary chair is placedy upon the upper surface of the conventional barbers chair so that the base member B will rest thereupon. The knob 2.4- is. then adjusted so as to cause the arm rests |'9 and` 20.` to move laterally outwardly away from the seat member 46 and the base member B' until they engagel the inner surfaces Ila, |2a of the side armsand I2 of the-conventional barbers chair C. This wi-ll positively fix thebase member'B and the seatmember 46 tothe Couven"v tionall barbers chair4 C. It. is an easy matter aesasse utilized as a crankto turn the head member 42 so as-to cause the shaft l40 to rotate about its longitudinal axis and thereby drive` the gear 4I which is in driving relation with the gear rack 28. Rotation of the gear ,4l will cause the seat member to raise o1' lower as desired. When cutting a childs hair, it is a simple matter for the barber to lower the conventional barbers chair to the lowest possible position and to then elevate the seat member 46 of the auxiliary chair tothe desired height so that there will be no interference of the barbers arms with the back of the conventional chair while the barber is performing the hair cutting operation. Through rotation of the head member `42 it is possible for the barber to adjust the elevation of the seat member 4B so that the head of the child will be at the desired level. .When so used, the clamp member l5, of course, is in retracted position so that the undersurface of the leg |5b will extend in the same plane as the general undersurface of the base member B.

When it is desired to utilize my auxiliary the stool S shown in Fig. 6, the knob I8 is merely turned until the leg |5b of the U-shaped clamp member I5 can slide beneath the seat of the stool and it is then tightened until the leg l5b will firmly engage the seat portion of that stool. This firmly secures the chair to a conventional stool which may be found in many homes and provides in effect a chair for a member of the family desiring to cut the hair of the other members of the family which simulates to a great extent and has all of the advantages of a conventional barbers chair.

It is obvious that if desired the adjustable control mechanism shown in Figs. 7 and 8 may be utilized instead of the adjustable control mechanism shown in Figs. 1-6 in order to elevate or lower the seat member 46. Turning of the knob 60 the desired direction will cause the seat member 46 to raise or lower as desired and will provide the advantages outlined hereinabove similarly to the adjustable control mechanism shown in Figs. 1 6.

Thus it can be seen that I have provided a novel and improved auxiliary barbers chair which may be cheaply constructed and is simple in operation. When using my auxiliary barbers chair in conjunction with a conventional barbers chair, the barber is enabled to quickly and easily secure my chair to the barbers chair in a positive manner so as to hold the auxiliary chair rigidly to prevent tipping of the same. As a result, the barber need not fear that the child whose hair is being cut may tilt or tip the chair upon which he is sitting and be injured as a result thereof. There is no possible way in which the child may cause the chair upon which he is sitting to become i disengaged from the larger conventional barbers chair.

In addition, my chair has the added advantage that the barber may lower the conventional barbers chair to such a low elevation that the back portion thereof will not be in the way of his arms during the hair cutting operation. The child may nevertheless be elevated through the use of my auxiliary chair to the desired elevation for convenient and relatively easy cutting of his hair. One of the severe strains upon a barber 'barbers chair with a conventional stool such as 65" is the` need for `his constantly maintaining; his arms at an elevated level and it is imperative that the head of hair being cut be positioned at vthe `most comfortable level so as not to tire the barber unduly during the hair cutting operation. If a barber must, during a hair cutting operation, hold his arms so as to avoid the relatively large back of a conventional barbers chair, he will soon become unduly tired.

My auxiliary barbers chair has the added'advantage that it may be used in the home in conjunction with a conventional household stool as a substitute for the conventiona1 barbers chair in the barber shop. -In other words, when K,my auxiliary barbers chair is attached to a conventional stool, it places for all practical purposes the advantages of a conventional barbers chair at the disposal of the home owner. may be elevated or lowered as desired relative to the stool and there is no possibilityof the chair becoming detached from the stool in view of the fact that the clamp l5 positively holds the same aflixed thereto.

My auxiliary barbers chair may also be utilized by the barber himself if he so desires by attach- Vchanges may be made inthe form, details, ar-

rangement and proportions of the various parts without departing from the scope of my invention.l
